thanks for the reply
what about those doucments that were required from the flyign school.heard that rule was scrapped so was confused.

cyrilroy21

Yup all those requirements were scrapped

All you need is an attested copy of your Indian CPL with the multi engine rating

I am really sorry about that.
I am going to study/studying from oxford aviation.Got the printout for the main books at real cheap rates...;)
about 3000 pages..:E

The only reason I got the prinouts is because I am unable to study via the computer screen.

Any more info?:ok:

Hi Guys,
Even I have filled up the form for the ATPL PAPERS (RADIO AIDS AND METEOROLOGY)
Am studying I C Joshi for MET and Oxford for Radioaids.
is it sufficient???

Help would be appreciated!

aadityaslg
16th Apr 2011, 18:18
I have heard "Keith Williams 1000 ATPL Questions" is really important.. but I am not sure if there is one for Met & Radio Aids.

There is one for Navigation for sure, another thing I don't understand is..
Is "Instruments" a part of the Radio Aids exam??

and which attempt have you filled in your form for??
I wish to appear for the Met paper this time.. will take it one at a time..
(don't even have a job yet so plenty of time in hand!)

yash
17th Apr 2011, 08:04
if anyone here has appeared for the ATPL radio exams can you please share if there were any questions asked on EFSI , FMS etc in previous papers ?

aviator7256
17th Apr 2011, 11:50
Even I have this doubt if instruments is a part of radio aids or not.
asked a couple of my friends and according to them-its not. but not sure.

I have filled the form for April attempt...
Even I don't have a job- so wanted to use the time...
M concentrating on MET, and will give the radio aids paper to know how is it like.
Lets see!

The DGCA website is a bit of a monster and attempting to follow logical paths such as "Personnel Licensing - Flight Crew - ATPL - Examination Syllabus" does not work.

The best path that I could find was "Personnel Licensing - Related Regulations - Flight Crew Licenses - Section 7 Flight Crew Standards, Training and Licensing".

This gives details of the syllabus for each examination, including the following.

2.1.2 Aircraft General Knowledge

a) general characteristics and limitations of electrical, hydraulic, pressurisation and other aeroplane systems; flight control systems, including auto-pilot and stability augmentation;

b) principles of operation, handling procedures and operating limitations of aeroplane power plants; effects of atmospheric conditions on engine performance; relevant operational information from the flight manual or other appropriate document;

c) operating procedures and limitations of appropriate aeroplanes; effects of atmospheric conditions on aeroplane performance;

d) use and serviceability checks of equipment and systems of appropriate aeroplanes;

e) flight instruments; compasses, turning and acceleration errors; gyroscopic instruments, operational limits and precession effects; practices and procedures in the event of malfunctions of various flight instruments;

f) maintenance procedures for airframes, systems and power plants of appropriate aeroplanes;



2.1.6 Navigation
a) air navigation, including the use of aeronautical charts, radio navigation aids; and area navigation systems; specific navigation requirements for long-range flights.

b) use, limitations and serviceability of avionics and instruments necessary for the control and navigation of aeroplanes;

c) use, accuracy and reliability of navigation systems used in departure,
en-route, approach and landing phases of flight; identification of radio navigation aids;.

d) principles and characteristics of self contained and external -referenced navigation systems; operation of airborne equipment;


But it may of course be out of date!

17th Apr 2011, 14:47
Yes radio aids and instruments are combined together in one paper. Equal proportion of questions are asked from each of them.

Expect lot of questions on EFIS,FMS, INS& IRS etc.

October 2010 attempt was full of questions from automation which includes autopilot, autoland, EICAS, EACM etc..But none of these topics were touched in January attempt only 5-6 Questions from automation.

To all who asked me for the place to get prinouts,NEHRU PLACE in NEW DELHI...:D
.75 rupees per page,I got about 2900 pages for about 2400,including spiral binding.
I cant explain the exact location of that particular shop,but its ground floor,probably meghdoot tower.The owner is a sardar uncle.Half of NIFT is present there all the time.:E

Could some one please explain ,how to solve this question

what will be the rate of descent when flying down a 12% glide slope, at a G/S of 540 Kts?

Thanks..

keith williams
18th Apr 2011, 11:41
The simple solution is to multiply the % gradient by the TAS in knots.

In this case it gives 12 x 540 = 6480 feet per minute.

This is an approximation based on another approximatrion that 1 knot - 100 feet per minute. (1 kont is really closer to 101.333 feet per minute).

Most questions of this type use a 3 degree glideslope. For this you must remember that the % gradient = 100 x tan descent angle. For 3 degrees this gives approximatley 5% gradient.

So for example a 3 degree glideslope at 100 knots requires 5 x 100 = 500 feet per minute ROD.

All of the above assumes nil wind.

5th Jun 2011, 06:16
Guys, I would appreciate if somebody could clear my doubt, this might be silly one but i am confused :confused:

Acc to DGCA syllabus , there are 5 papers (divided into 9 topics) for ATPL examination http://www.dgca.nic.in/misc/draft%20...bus(draft).pdf
whereas from ppl i am getting to know that there are just 3 papers
met, nav and radio aids (which includes instruments),
(this draft is issued since oct 2010, when its going to be implemented)
please please shed some info, how many papers are there and which section is included in which paper. DGCA :mad:

Maverick 03
5th Jun 2011, 17:49
Yes there are only 3 papers for DGCA ATPL...and also there has been a draft in place for reviewing about whether to increase the number of exams to 5.....but as it says it is a DRAFT.....
which means that it is a suggestion which is being considered and "looked upon" about the betterment of the aviation industry...just like the several other drafts which have been put up in last 5 years......which have ultimately failed or haven't ever reformed from being just a "draft" to a reality.....

If you look then you'll find that there is a similar draft for the CPL exams as well....but again it's just a Draft....

What happens is that when DGCA issues a draft, it sends its copy to all the flying clubs across the country and request the CFI's to come up with their suggestion and/also any changes they would like to suggest to make it better....but as far as I know...neither the CFI's, nor the DGCA is very much concerned about it and ultimately these suggestions and drafts end up in the dustbin.....

So if you are concerned whether this draft might come into force, then I would suggest that you take a chill pill becoz it will take much more time...and that too if DGCA is actually concerned about making any changes....

quick questionS to the professionals from a lowtimer :

Q)Radioaltimeter turns analog to circular at ____ ?:
1. below 1000feet
2.at or below 1000 feet
3.at DH

Q) what is the rhumb line track from A (4500N 01000W) to B (4830N 01500W) ?----Method to solve this question if described would be a great help!

capt.ace
9th Jun 2011, 12:03

thnx buddy.also i want to confirm that automation,fms,irs,ins,magnetism ,gyros are part of navigation? and instruments is combined with radio aids.

planeboy_777
9th Jun 2011, 12:47
Answer is B)
This happens in a 737 while landing .Check out youtube for this

for next question
this is a simple problem with trigonometry involved

Adjacent side is = C'long x 60 x Cos (lat) = (15-10) x 60 x cos (48.5) =198.7NM
Opposite side = Chlong x 60= 210NM

so the angle between ADJ and HYP is Tan (theta) = Opp/adj = 46.56deg
so at point from B to A is 090 + 46.56 = 136.56


which is 136 + 180 = 316 deg form A to B

thanks planeboy777,

for the second problem: can you also suggest how to find Great circle and Rhumb line distances also?.. between A (4500N 01000W) to B (4830N 01500W) ?

one more q)
A(equator, 59E), you travel on bearing 225 for 100 Nm, find new coordinates?
---- I know dlat comes to be 1deg10'..but not sure if my Dlong is correct , how to find Dlong here?

it would be helpful if someone could tell the answer for the following questions,
what is the difference between RNAV 1 and RNP1?
in enroute charts, why are some airports doesnt have localiser symbol, even though airport has ILS facility.
who issued the MOCA which is depicted on enroute chart ( jeppesen or state authority, ? how can we find out this? )

12th Jul 2011, 09:57
You dont need any hours post your CPL provided you have a multi endorsement on your Indian CPL

If you dont have a multi endorsement then you will need atleast 500 hours total time.

For the paperwork all you need is an attested copy of your Indian CPL along with the DD

flylikeaBE76
12th Jul 2011, 11:05
You've interpreted it wrongly. It's 500 hours total time in case of defense personnel only.

cyrilroy21
12th Jul 2011, 11:14
Lol you sure ?

I thought only the 200 hours PIC was for defence personnel

Anyway you still need a multi engine endorsement for writing the ATPL exams

Guys I am planning to give ATPL exams from October attempt. I have read the validity for the paoers which is 5 years but my query is that :- is every paper valid for 5 years or they are valid for 5 years from the result of the last paper. Plz help

Regards,
Jehan,

kush3370
13th Jul 2011, 05:28
@Jehan

Your Particular paper is valid for 5 years from the date mentioned on the result card (now a days it will be online). but the funda remains same. it doesnt have anything to do with your last paper's result.

for ex : Air Regulation showing date 10/07/2011 then its valid till 09/07/2016
and Navigation showing date 09/06/2009 then it is valid till 08/06/2014 .
so when you submit your papers to issue an ATPL, all the results should be with in their validity periods,

hope this helps...

capt.ace
13th Jul 2011, 05:29
all general subjects are valid for 5 years and technical (p1,p2,p3) are for 2 & half year.validity starts from the date which is mention on result card or date when result was declared

1) An a/c flying at 6000' enters the cone of confusion of a VOR. What is the diameter in nm of the cone. (this has got something to do with sin/tan/cos 40)

Radius of cone of confusion = A/C altitude (in NM) X Tan 50

and then radius X 2 to get the diameter of cone of confusion in NM. :ok:

2nd Aug 2011, 09:19
@ flyjet787 thanks for the reply!

Could anyone help me with conversion of glide slope in terms of % gradient to degrees? Here are some questions in terms of gradient:
1) a/c descends at 12% gradient, GS=540kts, find RoD
2) a/c maintains 5.2% gradient and is at 7nm from the RWY. Find the height of the a/c

Thanks again!

smurf84
2nd Aug 2011, 10:01
Mike Sierra - I think you can work it out this way.

Your descent gradient is 12% which is 0.12 times the groundspeed.

0.12 * 540 kts = 64.8 kts (Now, 1 knot = 101.33 feet/min)

So your ROD works out to be = 64.8 * 101.33 = 6566 feet/min

smurf84
2nd Aug 2011, 10:06
Mike Sierra - The answer to you second question could be worked out using the 1 in 60 rule.

Percentage gradient is the tangent of 5.2 deg * 100 = 2.977 deg

Height of the aircraft = 7/2.977/60 ( 1 in 60 rule) = 0.3473 Nm

Nm to feet conversion = 0.3473 * 6080 = 2111.58 feet

I hope it's correct.

keith williams
2nd Aug 2011, 11:03
As with all such problems it is best to try to get an understanding of what the information means.

A 12% gradient means that your vertical speed is 12% of your horizontal speed.

12% of 540 knots = 540 x 12 / 100 = 64.8 knots.

1 knot = 101.33 ft/min so 64.8 knots = 64.8 x 101.33 = 6566.184 ft/min.

Smurf84
Your method can be used but you made an error in converting the tangent into an angle.

Percentage gradient is the tangent of 5.2 deg * 100 = 2.977 deg

% gradient = 100 x tangent so for 12% the tangent is 0.12 as you have said.

But for a tangent of 0.12 the angle is 6.843 degrees.

Dividing this by 60 and multiplying by 540 knots gives 61.58 knots.

Multiplying this by 101.33 ft/min/knot gives 6240.40 ft/min.

The below are some questions from Oxford instrumentation book - objective revision 4 and 5.

Q1) An a/c is descending at a contant mach number. If the a/c is descending through an inversion layer, the RAS will:

a)remain constant
b)increase
c)decrease
d)decrease then decrease more slowly

Answer is b) increase.
however during descent in inversion, temp decreases at lower altitude. so, LSS decreases. since M.no = (TAS / LSS), therefore TAS should also decrease, in order for M.No to remain constant.
Yes, density increases at lower altitudes.
Now, RAS=(1/2)*density*(TAS squared).
Therefore effect of decreasing TAS is more, then increase of density.
so answer should be c) decrease.
Can anyone explain?

Q2)A perfectly frictionless DI, is corrected to give zero drift on the ground at 30 degree north. The DI is set to read 100 degree in an a/c stationary on the ground in latitude 45 degree north. The reading after 45 mins will be:

a) 92.33 degree
b)102.50 degree
c)97.78 degree
d) 103.75 degree

Q3) with constant drift during flight, the a/c heading will:

a)increase by more than 10 degree
b)decrease by less than 10 degree
c)increase by less than 10 degree
d)remain constant

Answer is b). what;s the logic?

You are making the mistake of assuming that the rate of decrease in TAS squared is greater than the rate of increase in air density (which determines the RAS at any given TAS.

LSS is proportional to the square root of absolute temperature so as we descend at constant Mach in an inversion, the decreasing temperature will cause the LSS and our TAS to decrease.

But as we descend both the increasing static pressure and the decreasing air temperature will cause the air density to increase. This will cause the RAS and EAS at any given TAS to increase.

The effect of the increasing density will be greater than the effect of the decreasing LSS so the overall effect will be that the EAS and RAS both increase while the TAS decreases at constant Mach.

You should be familiar with the simple ERTM graphs, which will enable you to answer this type of question in an exam without taking the time to go through all of the above arguments. If you do not have them please send me a PM and I will send them to you.

Q2)A perfectly frictionless DI, is corrected to give zero drift on the ground at 30 degree north. The DI is set to read 100 degree in an a/c stationary on the ground in latitude 45 degree north. The reading after 45 mins will be:

a) 92.33 degree
b)102.50 degree
c)97.78 degree
d) 103.75 degree



If you cannot answer this question then you need to study gyro errors before taking the exams.

In the northern hemisphere Earth Rate drift rate in degrees per hour is

Earth Rate in degrees per hour = -15 x Sin Latitude

The latitude net is designed to create a drift rate in the opposite direction to compensate for Earth Rate.

In the northern hemisphere Latitude Nut Rate drift rate in degrees per hour is

Lat Nut drift rate in degrees per hour = + 15 x Sin Lat Nut Setting

Adding the two together gives the total drift rate, which is

15 x (Sin lat nut setting – Sin latitude)

Multiplying this by the time gives the total drift.

Inserting the data from the question gives.

The gyro is said to be totally frictionless so there will be no random wander

So Total drift =( (+15 x Sin 30) + (-15 x Sin 45) ) x 0.75 hours

Total drift = -2.32995 degrees

Adding this to the initial heading of 100 degrees gives

100 – 2.32995 = 97.67 degrees.

The closest option to this is option c.


[QUOTE]
Q3) with constant drift during flight, the a/c heading will:

a)increase by more than 10 degree
b)decrease by less than 10 degree
c)increase by less than 10 degree
d)remain constant

Answer is b). what;s

As it stands this question makes no sense. But if we assume that it is the same aircraft as in the previous question, then because it is in the northern hemisphere the earth rate drift will always be a minus value. This will cause the heading to decrease. Only option b includes a decrease, so we do not need to look any further. But the question states that the aircraft is “in flight” so we really need to consider Transport wander. But the question does not give us enough information to do this.

Could anyone clarify about Mode 6 and 7 in EGPWS.

Mode 7 is for windshear alert below 1500 feet and gives windshear warning both during approach and takeoff.

similarly, Mode 6 gives bankangle warning. Is the bank angle warning only during approach or also during t/o?

I skipped a vital sentence from one of my earlier questions by mistake. I apologise. Here is the full question:

An INS equipped a/c flies from 56 N 20 W (waypoint 3) to 56 N 30 W (waypoint 4). With constant drift during flight the a/c heading will:

a) increase by more than 10 degree
b) decrease by less than 10 degree
c) increase by less than 10 degree
d) remain constant

Answer: b (How less than 10 degree?)

My explanation: Departure=335.516 NM

ERW comes to -12.435 degrees/ hr

TW = GS /60 * tan lat

How to calculate GS ?

keith williams
8th Aug 2011, 14:51
With that extra paragraph it is clear that this is not a gyro question. It is a great circle question (INS systems fly great circles).

It is asking for the amount by which the great circle track changes from A to B.

If you have not done these before I suggest you read up on Great Cricles and Conversion Angles. Then have a go at it.

When you post yourmethod and answer we can comment on it.

wings of fire
8th Aug 2011, 17:32
This is what I can make sense of. Unable to think beyond it.

Conversion angle=0.5*dlong *sin mean lat
=0.5*10*sin56
=4.145 degree(or 4 degrees)

so, initial GC track at waypoint 3(or 20 W)=(270+4)= 274 degrees

Now drift = angular difference between track and heading

HDG= 270 degrees (therfore drift= 4 degrees SB)

Similarly GC track at waypoint 4 (or 30 W) = (270-4)= 266 degrees

Here drift = 4 degrees port (assuming hdg remains 270)

echo.mike.india
8th Aug 2011, 18:57
i think the answer has to be "B"..
the heading is decreasing by approx 8.6 degrees..

cause when u depart from way point 3 your hdg is 274.3..
when you arrive at way point 4 your heading is 265.6 ...
so with constant drift throughout the flight...your hdd is decreasing by less than 10 degrees....i.e. 8.6...

please correct me if i am wrong...

keith williams
8th Aug 2011, 20:38
Your method and answer are correct Wings of fire.

But your comment that


Now drift = angular difference between track and heading


Is true when discussing drift in the normal sense, but this question isn't really about drift. I think that the examiner put in the words "constant drift" just to eliminate any unwanted complications. It would probably have been better to have said "in nil wind conditions".

The difference between the Great Circle track and the Rhumb Line track isn't realy an example of drift. At the start of this leg when the heading is 274.145, the track will also be 274.145 (assuming nil wind). And at the end of the leg when the heading was 265.855 the track will also be 265.855. But the average track over the whole leg would have been 270.

Hello keith. Can u solve this question. Again from radio aids oxford book- vor chapter.


Q4)what is the theoretical maximum range that an aircraft at FL 420 will obtain from a vor beacon situated at 400 feet above msl?
a) 225 nm
b) 256 nm
c) 281 nm
d) 257 nm

answer is a) 225 NM

My explanation:

Range = 1.25*(Root of ht + root of hr)

=1.25*(root of 400 + root of 42000)

= 281 NM

The first ones right.

But the second ans. is given as Increase by 6

keith williams
17th Aug 2011, 15:27
When taking the exam the most important thing is to select the correct answer.

When preparing to take the exam the most important thing is to learn the correct method.


The great circle track X - Y measured at x is 319°, and Y 325° Consider the following statements:
a Southern hemisphere, Rhumb line track is 322°
b Northern hemisphere, Rhumb line track is 313°
c Southern hemisphere, Rhumb line track is 331°
d Northern hemisphere, Rhumb line track is 322°



The important thing to remember here is because both the rhumb line and the great circle join the two points, the rhumb line track is the average of the great circle track at the two points. So in this question we just need to add the two together and divide by two to get (319 + 325) / 2 = 322.

Great circles are always convex to the nearest pole.

We have a great circle that is changing from 319 to 325, so we must be in the southern hemisphere. Sketch the situation if have difficulty visualising it.


A great circle track joins position A (59°S 141°W) and B (61°S 148°W). What is the difference between the great circle track at A and B?
a It increases by 6°
b It decreases by 6°
c It increases by 3°
d It decreases by 3°


For this one we need to use the conversion angle formula

The conversion angle is the difference between the great circle and the rhumb line.

Conversion angle = 1/2 x Sin mean latitude x difference in longitude.

In this case we have

Mean latitude = (59S + 61S) / 2 = 60S.

So Conversion angle = 1/2 x Sin60S x ( 148W - 141W)

If we use the conventions that

Latitudes North are positive
Latitudes South are negative
Differences in longitude to the West are positive
Differences in longitude East are negative

We get

Conversion angle = 1/2 x Sin -60 x 7W = -3.03 degrees.

The conversion angle is the difference between the great circle and the rhumb line so at position A the great heading is 3.03 degrees less than the rhumb line.

But the great circle and the rhumb line meet at positioon B so the great circle heading must gradually increase until it becomes 3.03 degrees greater than the rhumb line.

Starting 3.03 less and ending up 3.03 more, the great circle must have increased by 6.06 degrees.

If the use of plus and minus values is too confusing, then simply sketch the situation.

Great circles are always convex to the nearest pole.

We are in the southern hemisphere so the great circle initialy heads south of the starting point then gradually curves to the north until it reaches the second position. We are going west so this curving must represent a gradual increase in heading.

So the answer to this question is increasing by 6.06 degrees.

b 73.5 NM
c 78 NM
d 110 NM

if you do know..you might as well post the solution

keith williams
18th Aug 2011, 08:51
AZAX,

Instead of simply giving you the solutions, I have provided two very similar questions and worked solutions below.

Please go through these and then try to answer your two questions.



SCALE 6.
On a direct Mercator projection, at latitude 45° North, a certain length represents 70 NM. At latitude 30° North, the same length represents approximately?

a. 86 nm.
b. 75 nm.
c. 45 nm.
d. 90 nm.


This type of problem can be solved using the standard equation:

Distance at A / Distance at B = Cos A / Cos B

This can be rearranged to give:

Distance at B = (Distance at A x Cos B) / Cos A

Where A and B are latitudes.

For this question use A = 45 N, and Distance at A = 70 nm
And B = 30 N, and distance at B is to be calculated

Inserting these values into the equation gives:

Distance at B = (70 nm x Cos 30) / Cos 45 = 85.73 nm or approximately 86 nm (option a).


CHART THEORY 8.
What is the constant of the cone for a Lambert's Conic projection whose standard parallels are at 50 degrees North and 70 degrees North?

a. 0.866.
b. 0.500.
c. 0.941.
d. 0.766.

The constant of the cone is equal to the sine of the parallel of origin.

The parallel of origin is midway between the two standard parallels.

So in this question

Parallel of origin = (50 + 70) / 2 = 60N

Constant of the cone = sine of 60 = 0.866 (option a).

During the last half of the Nav paper, the invigilators came in and said, "We have got a message from DGCA and they say that you can leave the hall and your computers as it is"

so when some asked, is it cancelled?

they say we don't know but they say you can leave the hall.

Many students couldn't log in the system at all for the entire 2.5 hours until this message was broadcast'ed.

Heard that this question was asked twice in the same paper of radio aids atpl

cyrilroy21
28th Aug 2011, 12:27
Q " What does swept gain mean in an AWR "

1. Transmission power increases as range increases

2.The returns are stronger at large angles from the aircraft heading

3. Transmission power increases as the cosecant2 of the angle from horizontal

4. The receiver increases sensitivity with time


Correct answer is 4) The receiver increases sensitivity with time

Taken from GSP Radio Aids :ok:

'During the climb after take-off, the altimeter setting is adjusted at the transition altitude. If the local QNH is 1023 hPa, what will happen to the altimeter reading during the resetting procedure ? '

a) It will decrease
b) It will increase
c) It will remain the same
d) It is not possible to give a definitive answer

The answer for the above q. is
IT WILL DECREASE.:ok:

keith williams

If you think about how the altimeter works and how pressure varies with altitude, this type of question is not at all difficult.

The altimeter indicates the height of the aircraft above whatever pressure level is set on the subscale.

With 1023 set it indicates height relative to the 1023 level.

With 1013 set it indiactes height above the 1013 level.

Pressure decreases with increasing altitude so the 1013 level is above the 1023 level.

So when adjusting from 1023 to 1013 we are adjusting it to read relative to a higher level.

So the indication will decrease.

@cyril, are all the answers on the Aviation Training site accurate? KW has (some of their Qs) different answers for similarly worded questions with the same choices.

cyrilroy21
4th Sep 2011, 12:12
I cant vouch for the accuracy of the answers on the site .

I believe a few errors have crept in here and there . You can contact the website founders and discuss any questions you have with them .
They reply back quickly

On another note I believe Keith Williams question banks also have some errors in it . I remember him mentioning it earlier somewhere on the forum

keith williams
4th Sep 2011, 12:38
I doubt if any question bank is entirely free of errors.

It is also the case that some apparently identical questions are in fact slightly different and have different answers. Recent additions to the JAA question bank have included a lot of questions of this type. In many cases you are given two statements and must decide whether each is correct or incorrect. Unless you read these questions very carefully you will probably pick the wrong answer. As an exampe of this there are something like 20 to 30 questions on how pressure and velocity vary in a venturi.

The most important thing to look for in a good question bank is detailed explanations. This will enable users to develop a proper understanding of the subject material, and will also enable them to make a rational judgement about whether or not an answer is correct. But most importantly, by developing a real understanding of the subjects, it will enable exam takers to deal with questions that they have never seen before.

The majority of the questions that are posted on this forum are from people who want to know how to solve problems. Question banks that provide the question and answer, but no explanation are of no help whatsoever in this regard.

Are you sure that you are comparing identical questions?

The closest that I can find to the one you describe is question number 578 in the AUTOFLIGHT section of INSTRUMENTS in my CD. In this question each of the options has at least 3 statements listed as being correct and some of them have 4. It is not possible to select 1,2 in this question.

If you have studied a recognised set of ATPL course manuals you should have no problem in identifying the correct answer to this question. If you have not done so then a GOOGLE search for AUTOLAND or AUTOMATIC LANDING SYSTEMS may help.

The term "FAIL SURVIVAL" is not a recognised autoland system failure mode.

I have listed the recognised modes and their meanings in the explanation to this question in my CD.

matthewgamm
5th Sep 2011, 15:52
@Keith, thanks for the explanation.
However, I did look up the term "Fail Survival" on google, and it stated that it is the same as "Fail Operational", which is why I was unclear on what the correct choice of answer is, for that particular question.

Some more:

1. At sea level, on a typical servo altimeter, the tolerance in feet from indicated must not exceed:
a. +/-60 feet
b. +/-30 feet
KW answer: b
AT answer: a

2. The altitude indicated on board an aircraft flying in an atmosphere where all the atmospheric layers below the aircraft are warm is?
a. Higher than the real altitude
b. Lower than the real altitude.

Both, KW and the AT site mark (a) as the answer; however, in a similarly worded question, only difference being in the end, instead of "below the aircraft are warm", this question reads "...below the aircraft are cold", and KW still marks the answer as "Higher than the real altitude".

What are the correct answers for them both?

3. With a constant weight, irrespective of the airfield altitude, an aircraft always takes off at the same?
a. EAS
b. CAS
c. TAS
d. GS
The site marks (b) as the answer.

Another similarly worded question on the site:
With constant weight and configuration, an aircraft always takes off at the same?
a. EAS
b. TAS
c. IAS
d. GS
Here, the site marks (a) as the answer.

4. The altimeter is supplied with?
a. Static pressure
b. Dynamic pressure
Answer marked is (a)
Another similarly worded question on the site:
Given:
Pt = Total pressure
Ps = Static pressure
Pd = Dynamic pressure
The altimeter is fed by:
a. Pt - Pd
b. Pd
c. Pd - Ps
d. Ps - Pt
Answer marked is (b)

5. Given:
Ts is the static temperature (SAT)
Tt is the total temperature (TAT)
M is the Mach number
The total temperature can be expressed approximately by the formula:
a. Tt = Ts(1+0.2KrM2)
b. Tt = Ts(1+0.2M2)

KW answer: (a)
AT site answer: (b)

6. Following 180° stabilized turn with a constant attitude and bank, the artificial horizon indicates?
a. Too high pitch up and correct banking
b. Too high pitch up and too low banking

My answer: (a)
AT site answer: (b)

7. A turn indicator is built around a gyroscope with?
a. 1 degree of freedom
b. 2 degrees of freedom

My answer: (a)
AT site answer: (b)

I have carried out a search of my CD and have found the following:

1. At sea level, on a typical servo altimeter, the tolerance in feet from indicated must not exceed:
a. +/-60 feet
b. +/-30 feet
KW answer: b
AT answer: a


The correct answer to this question is +- 30 feet as stated in my CD. Older mechanical altimeters achieved something like +/- 60 feet.

2. The altitude indicated on board an aircraft flying in an atmosphere where all the atmospheric layers below the aircraft are warm is?
a. Higher than the real altitude
b. Lower than the real altitude.

Both, KW and the AT site mark (a) as the answer; however, in a similarly worded question, only difference being in the end, instead of "below the aircraft are warm", this question reads "...below the aircraft are cold", and KW still marks the answer as "Higher than the real altitude".

What are the correct answers for them both?


In the ALTITUDE section of the INSTRUMENTS questions I found the following:

Questions 71, and 91 refer to air that is warmer than standard. In both cases the answers state the the altimiter indication will be too low. These are the correct answers.

Questions 70, 92 and 100 refer to air that is colder than satnadrd. In both cases the answers state that the altimeter indication will be too high. These are the correct answers.


5. Given:
Ts is the static temperature (SAT)
Tt is the total temperature (TAT)
M is the Mach number
The total temperature can be expressed approximately by the formula:
a. Tt = Ts(1+0.2KrM2)
b. Tt = Ts(1+0.2M2)

KW answer: (a)
AT site answer: (b)


In the TEMPERATURE section of INSTRUMENTS question 892 asks for the correct equation. This (like all of the other questions in my CD) is a real JAA CQB question. None of the options include Kr. When taking the exam you can only pick from the options listed. Because none of them included Kr it is not possible inlcude this in your answer. The answer given in my Cd is the most correct of those offered in the question.

In reallity the correct equation is Tt = TS(1 + 0.2KrM squared) where KR is the Ram Recovery Factor for the total air temperature probe. For a modern Rosemount Probe Kr is 1 and this is why it is often omitted from the equation. This is probably why the author of the question omitted it.



Following 180° stabilized turn with a constant attitude and bank, the artificial horizon indicates?
a. Too high pitch up and correct banking
b. Too high pitch up and too low banking

My answer: (a)
AT site answer: (b)


In the GYROS section of INSTRUMENTS question 301 indicates that the correct answer to this question is "Too high pitch up and too low bank angle". This is the correct answer.

Your comments appear to have misquotedmy CD on a number of occasions. This may be related to the fact that you are using option letters to indicate the answers. Each time you select a question in my CD the program reshuffles the options. This means that the correct option letter is different every time. But the correct answer is indicated each time.

If the above comments have not clarrified the situation sufficiently please indicate the numbers of the questions to which you refer. I can then look at them again.

I have not commented on the AT website answers because I have not looked at it in any detail. Having looked at it very briefly I observed that it does not provide any explanations. Because of this I immediately lost interest in it.

Keith, I don't have any of your CDs; I do, however, have your "Instruments" book, but the 2005 revision.

If you have access to that book, have a look at page 51, Qs 4 and Q7. The answer to Q7 is incorrect; the correct answer (according to you, and which is correct) is (d).

In the GYROS section of INSTRUMENTS question 301 indicates that the correct answer to this question is "Too high pitch up and too low bank angle". This is the correct answer.Have a look at page 123, Q12.
The answer marked (and I agree, that it is correct) is (c). How then, is the answer to the question posted "Too high pitch up and too low bank"?

Your Instruments book doesn't seem to cover topics such as VOR, DME, ADF, Radar, ILS, etc. Do your other books cover these?

Thanks for taking the time to reply to the questions posted. I appreciate it.

The correct equation includes Kr so if the options include Tt = Ts(1 +0.2 KrMsquared) you should select it. But if none of the options include KR then you should select Tt = Ts(1 + 0.2Msquared).

Keith, I don't have any of your CDs; I do, however, have your "Instruments" book, but the 2005 revision.


OK now we can understand each other.

If you have access to that book, have a look at page 51, Qs 4 and Q7. The answer to Q7 is incorrect; the correct answer (according to you, and which is correct) is (d).


Q4 is about cold air and the correct option is option d which is, "Higher than the real altitude".

Q7 is about warmer air and the correct option is option d which is, "Lower than the real altitude".

They are both correct and there is no contradiction. Are you perhaps being thrown by the fact that both correct answers are option d?

In the GYROS section of INSTRUMENTS question 301 indicates that the correct answer to this question is "Too high pitch up and too low bank angle". This is the correct answer.
Have a look at page 123, Q12.
The answer marked (and I agree, that it is correct) is (c). How then, is the answer to the question posted "Too high pitch up and too low bank"?


Sorry I have misquoted my own Cd in my previous post. Both Q12 in the book and Q301 in the CD give the same answer which is, Too high pitch and bank angle correct". Both the book and the CD are correct.


Your Instruments book doesn't seem to cover topics such as VOR, DME, ADF, Radar, ILS, etc. Do your other books cover these?


My books were written for the JAA exams but then the DGCA started to take a large number of questions from them for their own exams. In the JAA system Radio Navigation and Instruments are two separate examinations. The subjects that you have listed are in Radio Navigation in the JAA system. I have not yet written a book for Radio Navigation but my CD covers all of 14 fixed wing subjects plus Helicopter POF.

@aviatorz

Until now only 3 papers to clear
1. General navigation
2. Radio aids & Instruments
3. Met

Oral exam is only for nav and radio. no orals for met

you have to secure 70% marks in both oral and written not combined.
90 marks for written and 10 marks for orals..total 100
min passing marks in 63 for written and 7 for orals..

you have to get these minimum marks to pass in the subject .

after you give written exam for all three
after few days (about a month even though its online now) they will declare who all has got minimum 63 in written and put up a list of all those who can appear for the oral.

after orals are over you will get your final result which is declared with the cpl results.
they will give you your written marks and oral marks.
if you manage to get the minimum required to pass i.e. 70% in both of them separately, then only you clear the paper.

thanks

echo.mike.india
17th Sep 2011, 05:30
you can appear for all three papers separately also
if you clear written you will get 3 attempts to clear orals
if you still not clear orals you will have to give written again.

i would recommend you to give nav and radio together ..cause if you clear both written in one go..then only one (combined) interview is held for both of them.
its more easy to clear both the papers in one go this way.

study oxford and KW questions. and gsp
do all the back questions of oxford and gsp...

these questions banks will help you clear your written...
but your basic knowledge will be tested in the orals...

Hi Folks, i was going through the Oxford ATPL, Principles of flight and found a few statements which, i cant seem to understand. I feel they contradict each other so please advice if i'm reading it wrong.

1. Chapter- Drag > Parasite drag> skin friction
"Because of the adverse pressure gradient existing on a curved surface, the transition point will be further forward than if the surface was flat"

2. Chapter- High Lift Devices> Leading Edge Flaps
"On high speed aerofoil sections the leading edge may have very little camber and have a small radius. This can give flow separation just aft the leading edge at quite low angles of attack"

Now which of the above is right and is there something i'm missing in the above concepts?

Also - i dont seem to see the definition for Form drag : "Because of separation there will be a lower pressure at the trailing edge than the leading edge. An aerodynamic force will act in the direction of the lower pressure - form drag"
How would this be a drag if there is airflow from the leading to the trailing edge? wouldnt this infact contribute to the thrust for the aerofoil?
I understand the concept of adverse pressure gradient but the above reason has been quoted as a separate factor.

thanks in advance.

cheers,
P

If u r giving both your orals together, they will either pass you on both the subjects or they will fail you on both. Never heard if they just pass on one if u r giving both the orals together. That's from my experience. Any ways do inform us how your oral goes.
For General Navigation - you should have mastery over maps and charts.

wings of fire
21st Sep 2011, 18:13
Thrust acts in the forward direction. Drag acts in backward direction.


Form drag: Because of the adverse presuure gradient behind the transition point, there is decrease in kinetic energy of lower levels of boundary layer.Whereas the upper level of boundary layer overrun at this point(called seperation point). Because of seperation, Pressure at trailing edge < Pressure at leading edge. This force acting backward is form drag.

Thrust is a force and force=ma. In case of form drag, kinetic energy of lower boundary layer decreases. so acceleration is reduced and therfore thrust gets reduced.

wings of fire
21st Sep 2011, 18:52
Also see page 7-11. Your concepts will be much clear by reading stalling chapter thoroughly.

Generally sharper the nose , thinner the aerofoil section, the more sudden will be the stall.

Also there are 4 reasons of stall(or seperation)
1)leading edge radius
2)Camber
3)Thickness to chord ratio
4)Chordwise location of maximum thickness and max camber

Transition pt. is the point where airflow changes from laminar to turbulent.

As AOA increases, adverse pressure gradient increases and transition point will move forward.

Statement: 2. Chapter- High Lift Devices> Leading Edge Flaps
"On high speed aerofoil sections the leading edge may have very little camber and have a small radius. This can give flow separation just aft the leading edge at quite low angles of attack"

High speed aerofoils can stall at low aoa (that means when their speed is high). Just imagine if leading edge flaps are not put in those aerofoils, then how will these a/c's slow speed and land at the airport(as they will require high AOA during landing.)

24th Sep 2011, 15:14
Thanks for the attempt to clarify, but i do understand all the concepts you're explaining, my question however was completely different.

I meant to say that the first two statements i mentioned seem to contradict themselves because one says the transition point/separation point would be much further ahead since the aerofoil is not a flat surface (translating to flatter the aerofoil/ surface more aft the separation )
The second says the separation is just aft the leading edge because the surface has less curvature. This would imply if the aerofoil had more curvature, the separation would be much further aft (hence contradicting the first statement)

I do understand the thrust and drag definitions but when there's a force acting from the leading edge toward the trailing edge - how would that be a drag?

thanks again in advance.

cheers,
P

I was asked this question in the orals..
The reference signal is 90deg, variable signal is 240deg. What is the phase difference ?
(please do not say it's 150deg)

I would appreciate if anyone presents a solution to this one..(it's using the graph).
I couldn't fgure it out in my Class 11 either :ugh:

golfpapa
30th Sep 2011, 10:59
i think the answer is 90 plus 180 minus 240 = 30deg.

always subtract variable signal from reference signal and anytime reference signal is smaller than variable add 180 to reference signal and then subtract.

I am not sure if this method is correct just an inference i hv drawn after seeing the correct answers to these type of numericals

if phase_diff > +180 then
phase_diff = phase_diff-360

else if phase_diff <-180 then
phase_diff = phase_diff+360

else
phase_diff = phase_diff

in this phase_diff= ref - variable= 90-240= -150

-150 is less then -180

so phase diff= -150+360=210

1. At the second stage of integration, E/W speed is converted to E/W distance gone. To convert this departure into change of longitude, it has to be:
a. Multiplied by the Secant of the latitude
b. Divided by the tangent of the latitude

2. The amber ALERT light on an INS Control and display unit:
a. illuminates steadily for 2 minutes before reaching the next waypoint
b. start flashing 2 minutes before reaching the next waypoint and goes out at 30 secs to run.

The answer to the first question can be derived from the Departure equation.

Departure = Change in longitude x cosine of latitude.

Dividing both sides by cosine of latitude gives

Departure / cosine of latitude = Change of longitude

The secant of an angle = 1/cosine, so dividing by the cosine is the same as multiplying by the secant.

So departure x secant of latitude = Change of longitude.

Deriving answers is this way will enable you to develop a far better understanding of the subjects.

Q1. A great circle has its North vertex at 70N130E, at what longitude and in what direction would the great circle cross the equator assuming:

a. Initial direction is east from the northern vertex{ans-140W 160{T}}

b. Initial direction is west frm northern vertex{ANs-040E200{T}}

Q2. Given that the compression value of the earth is 1/297 and that the semi major axis of the earth,measured at the axisof equator is 6378.4km,what is the semi major axis of the earth measured at the axis of the poles?
ans- 6356.9km

Q1. A great circle has its North vertex at 70N130E, at what longitude and in what direction would the great circle cross the equator assuming:

a. Initial direction is east from the northern vertex{ans-140W 160{T}}

b. Initial direction is west frm northern vertex{ANs-040E200{T}}




The centre of any great circle is at the centre of the Earth. This means that.

1. The vertices are at diametrically opposite latitudes. With one at 70N the other must be at 70S.

2. The vertices are at 180 degrees of longitude apart. With one at 130E the other must be at 050W.

3. The great circle crosses the Equator midway between the two vertices. With one vertex at 130E and the other at 050W the great circle crosses the equator at 040E. The second crossing point is 180 degrees of longitude away, which is at 140W.

The two vertices are at 70N and 70S, so a straight line (great circle) between the two crosses the Equator at an angle of 70 degrees (this is based on the definition of latitude).

This means that the great circle crosses the local meridians at the Equator at an angle of 20 degrees (which is 90 – 70 = 20).

This in turn means that the true tracks at the equator are 180 + 20 = 200 and 180 – 20 = 160.

If you do a simple sketch of the situation you should be able to see that the answers are as stated in your question.


Q2. Given that the compression value of the earth is 1/297 and that the semi major axis of the earth,measured at the axisof equator is 6378.4km,what is the semi major axis of the earth measured at the axis of the poles?
ans- 6356.9km


A compression of 1/297 means that the smaller axis is 296/297 of the larger axis.

So the answer is 6378.4 km x 296/297 = 6356.9 km.

Meteorology Query

At FL180, the air temperature is 35 degree C, The air density at this level is-

a.Equal to density of ISA at FL180.
b.Unable to determine without knowing the QNH
c.Greater than density of ISA at FL 180
d. Less than density of ISA at FL 180.

I'm looking for an explanation to the answer. Thanks.

At FL180, the air temperature is 35 degree C, The air density at this level is-

The actual temp at FL180 is higher than standard. Hence, air will be less dense
d. Less than density of ISA at FL 180.

The answer marked is (c)

I assumed the same reason as you. Not sure if the answer stated is wrong out there.!

And about the ATP papers, I haven't read it anywhere myself just a quote from friend says the attempts need not be consecutive and should be within 2 years of clearing written exams.

Thanks in Advance:ok:

sperry - I think they still require attested copies of your Indian CPL with multi-endorsement? I'm not sure by just giving out the details of your licence, you would be permitted to sit for the exam. Try collecting your licence from the DGCA within the next 10 days, get an attested copy and then submit it along with the ATPL exam application form.

sperry - I haven't heard of anything like that before. If I haven't prepared well enough for Navigation or Radio Aids (as both of them have an oral examination), Meteorology would be the first exam on my list. Then I'll give it some time for the other two subjects. But it's your decision at the end of the day. Good luck bud !

As long as the hard copy of documents reaches DGCA before the last date i.e. 31st October, It doesn't matter 10 days or 15 days.

superdunkaroos

For a Final Clarification on dates!
Guys,

Oct 31st is the last date for ONLINE SUBMISSION of the form.

The print out plus the other attachments aka DD, Attested CPL + M.E. Page + Photo should reach max within 10 days of Application online.

No need for DHL etc, Just Speed Post it.

If in Delhi, Speed Post reaches the Very Next Business Day.

takes a Max of 5 days from anywhere else in India to Reach their office in Delhi.

Costs a Max of 12 - 25 Rs. Depending on Location.

Thanks. :)

Sorry guys to break the sequence, but I have a query which I need to clear.

I have a CPL with Multi-Engine rating endorsed and I have got a job to fly a single engine turbo-prop.
My question is that will my hours of flying this machine be counted towards my ATPL (as I have read that ATPL cannot be issued on Single engine).

And just to get the knowledge what is the scene like in the industry with someone who has some decent number of hours on single engine turbo?

Thanks in advance.
